Open source game
An open source game can simply be defined as a game, which is open source software. However, this definition leaves important questions unanswered:
- Is the source code freely licensed?
- Does the source code depend on non-free libraries?
- Are the art assets open source?
- Are the assets available together with the source code?
- Are the assets freely licensed?
- Are the assets available in non-proprietary file formats?
Using the term free, open source game (foss game) can imply that at least the source code is freely licensed.
A method to express that code and assets are freely licensed, is to refer to DFSG-compliant game, which implies that DFSG-compliant licenses are used for both.
